《中学数学月刊》1999年第6期《一个三元不等式链》一文中有如下两个不等式：由于不等式（2）不成立（见《中学数学月刊》1999年第10期《一个不等式键的探究〕一文），所以原不等式链显得不完整．笔者经过探究，发现不等式（1），（2）之间的立十字十换为后可使原不等式链变完?
There are two inequalities in the article “Chain of a Triple Inequality” in the article “Middle School Mathematics Monthly”, No. 6, 1999: Inequality (2) is not established (see “Introduction to an inequality key” in Middle School Math Monthly, 1999, Issue 10). A), so the original inequality chain is incomplete. The author after investigation, found that inequality (1), (2) between the vertical cross ten for the original inequality chain can be completed?
